Application led September 23, 1920. Serial No. 412,237.

To all whom t may concern.'

Be it known that I, FRANK H. DILLoN, a citizen of the United States, residing at Rock Island, in the county of Rock island and State of Illinois, have invented certain new and useful Improvements in Smoke Consumers, of which the following is a specifica tion.

My invention relates to improvements in smoke consumers and is applicable to vertical tubular boilers and heaters of various kinds.

The objects of my invention are to pro-- vide a smoke consumer which can be readily applied to new or old vertical tubular boilers and heaters and be readily operated and controlled and will effectively consume the smoke therefrom.

I attain these objects by the mechanism illustrated in the accompanying drawing in which- Figure 1 is a vertical section of a vertical tubular boiler with my apparatus at.- tached thereto.

Figure 2 is a top view of such boiler with the smoke stack removed.

Figure 3 is a detail showing the operat ing lever for the movable plate of my device.

Figure a is a detail of the stationary plate and Figure 5 is a detail of the stationary and movable plates, nozzle and fastening therefor.

Similar numerals refer to similar parts throughout the several views.

My apparatus includes a series of air pipes, 5, having their outer ends secured in a stationary plate, 6, and their inner ends bent substantially at right angles so as to enter the upper end of the lines, 3, preferably and extending through the tlues, 3, although they may terminate shortly below the top of the liues. rlhe stationary plate, 6, may be secured to the boiler or to the smoke stack by the brackets, 8, and 9, or any other suitable means. The stationary plate, 6, is preferably formed with flanges, 6b, to form a track for a movable plate, 7, to slide therein. The stationary plate is provided with a series of openings, 6, at the ends of the air tubes, 5. The movable plate, 7, is provided with a corresponding series of openings, 7a. Steam nozzles, 12b, are secured to the movable plate, 7, by brackets, 10, or other suitable means and are set in close proximity to the opeir ings, 7, or may project slightly into these openings if desired. The outer end of each steam nozzle is connected to a steam pipe. 1,3, which is provided with a valve, 14a, by which the steam may be regulated or shut oli' and which may be connected to the boiler by any of the well-known means which will allow a slight movement of the steam pipe, 13, either by springing the pipe, 14, or by a iieXible joint. I

The air pipes extending from the stationary plate to the boiler flues are made smaller than the internal diameter of the tlues so as to leave a small space surrounding those pipes which may extend through the entire length of the tlues or merely project into the upper end thereof as desired. l consider it preferable to have them extend the entire length of the flue and project a short distance in order to avoid, the cooling effect of the air upon the flues.

The number of air pipes may be varied to suit each individual case. In the ordinary sized vertical boiler, four air tubes will be suthcient and they should be spaced approximately equal distances apart and as near the center of the boiler as conditions will permit.

An air regulating valve, 12, is mounted upon each nozzle, 12b, and secured by set screw, 12a, which may be adjusted to restrict the amount of air carried into the openings, 7a, as desired.

If desired, a boX cover or manifold may be secured to the movable plate to silence the noise of the steam from the nozzle, but in ordinary practice, such a manifold is not necessary as the nozzles need not be opened wide enough to cause an objection-- able hissing or ringing sound from the steam.

A lever, 16, is fulcrumed at 17a on a suitable support, 17, secured to the boiler, and has one end formed for an operating handle to be operated manually, the other end connected by a link, 15, to one end of the movable plate so that the `plate may be` moved lengthwise by means of the lever.

In the operation of my device, steam or compressed air is admitted to the nozzles by opening the valve, 14a, a short distance. Ordinarily one-eighth or one-fourth of a turn of the valve will be sufficient and it should be opened only to the smallest eX- tent which will furnish suliicient steam to produce the desired result as too much steam pressure will inject too much cold air into the furnace for the best results.

In the ordinary vertical boiler, sufii'cient air can be fed to the fire by three or four air tubes extending down through the flues as shown and as the boiler will contain a much larger number of flues, the flues not used for -air tubes, will furnish adequate draft. In ordinary construction, by the use of my device, the quantity of smoke will be so reduced that the use of three or four flues for air tubes will still leave ample draft through the remaining flues.

In the drawings, I have shown only five flues, but it will be readily understood that the 'ordina-ry vertical boiler contains from a dozen to twenty flues and from that upn wardsto a much larger number.

When fire is just being started in the boiler,'the air' openings, 13a, should be entirely closed by the movable plate, 7 and may be opened as soon as a pressure of four or ive pounds or more has been developed in the boiler. In practice, the use of this consumer not only facilitates the draft and consumes the smoke, but keeps the 'lines free from soot, thereby increasing the heating capacity of the boiler and making a considerable saving of fuel. While my device isdesigned principally for the use of soft coal, it may be used to good advantage with crude oil or any other fuel "which is likely to produce considerable quantities of smoke or soot.

In arranging the'air `tubes in the fines, I

yprefer to insert the air tubes in the flues at approximately the middle of the boiler. The effect of the blast of air coming downward ythrough these tubes will be to hold the gases upon the incandescent coals until they have been consumed and toA 'deflectthe major portion ofthe combustion toward the side walls of the boiler and thus procure the largest possibleheating effect from the combustion, as theheat will be transmitted through the walls of the fire box into the water leg as well as through the crown sheet and flues.

I claim:

1. In a smoke consumer for vertical tubular boilers, the combination with an air tube, havingA one end secured in a flue of such boiler to discharge at the lower end of thc i fine, :and its outer end extending through ythe walls ofthe'smoke stack thereof, of a steam nozzle mounted adj acent the outer end of the air tube, an air regulating valve mounted on the nozzle and a movable damper plate mounted adjacent the outer end of the air tube.

2. In a smoke consumer for vertical tubular boilers, the combination with a series of air pipes having their inner ends extending into boiler fines therein to discharge at the lower end of the flues, of a series of steam nozzles mounted adjacent the outer ends ot' said air tubes, air regulating valves mounted on the nozzles and a movable damper plate.

3. In a smoke consumer for vertical tubular boilers, the combination with a series of air tubes having their inner ends respectively extending into lines of such boilers ada )ted to discharge at the lower end of the tues, and their outer ends secured tuljaeent corresponding openings in a stationary plate, of a series of steam nozzles mounted adjacent the openings in the stationary plate, air revu lating valves mounted on the nozzles an a movable damper plate mounted adjacent the outer ends of the air pipes.

4. In a smoke consumer for vertical tubular boilers, the combination with an air tube, having one end secured in a flue of such boiler adapted to discharge at the lower end of the flue and its outer end extending through the walls of the smoke stack thereof, of a steam nozzle mounted adjacent the outer end of the air tube, an air regulatin valve mounted on the nozzle, a movable amper plate mounted adjacent the outer end of the air tube, and a lever to operate the plate.

5. In a smoke consumer for vertical tilbular boilers, the combination with a series of air pipes having their inner ends extending through boiler iues therein, of a series of corresponding steam nozzles mounted adjacent the outer ends of said air tubes, air regulating valves mounted on the nozzles, a movable damper plate mounted adjacent the outer end of the air pipes, and a lever to operate the plate.

6. In a smoke consumer for vertical tubular boilers, the combination with a series of air tubes having their inner ends respectively extending through fines of such boilers and the outer ends secured adjacent corresponding openings in ay stationary plate, of a series of steam nozzles mounted adjacent the open ing in the stationary plate, air regulating valves mounted on the nozzles, a movable damper plate mounted adjacent the stationary plate and a lever to operate the plate.

In testimony whereof I aix my sifrnature.
